Summary:An example operation may include one or more of receiving, by a full storage peer of a blockchain network, a blockchain transaction, executing chaincode to create a new world state for a blockchain, transferring, in response to the blockchain transaction, partial Merkle tree hashes to one or more partial storage peers, the partial Merkle tree hashes corresponding to the blockchain transaction, verifying a current world state hash with the partial Merkle tree hashes, receiving, by the one or more partial storage peers, chaincode arguments, executing chaincode on the chaincode arguments to generate a new world state, calculating a new world state hash, and performing consensus, by the full storage peer and the one or more partial storage peers, on the new world state hash.
